After seeing all the abused, mangled, and broken Soma variants that came out, László Molnár came to the conclusion that 90/90 is so 2020. Using his acute sense of puzzle design mastery, he determined that something was wrong with the angles of these variants and decided that they couldn’t be right all the time. Utilizing the rombic tetrahedra grid of BurrTools, he found a cut that was above the rest and created Halfcut Soma - once again proving the adage that you can still appear sharp even if you’re not right.
Like so many unfortunate Soma cube victims before, the design process commenced with picking on the smallest piece of the group. The tri-cube was once again targeted and dissected into 6 pieces. This time however, László cut the 3 cubes at 45 degrees before gluing each triangular half-cube to one of the other 6 pieces. This could have been the end of it, but László obviously decided that this puzzle would be too easily solved by discriminating Soma puzzle enthusiasts who have been crunching through many variants over recent years.
The objective of the puzzle remains to fit the pieces into a 3x3x3 space. Of course, with all those half-cubes thrown out, there are a lot of holes in the resultant cubic space. László also ensured that there was a single solution to maximize your enjoyment.
Solving the Halfcut Soma is a nice challenge! Enough information is provided for you to solve it with a logical approach and a little experimentation. Even so, it takes a while to warp your mind for working with pieces made with triangular segments instead of cubes. Taking a logical approach is not mandatory and you’re welcome to disregard it and enjoy the puzzle for a longer time.

It’s picnic basket season again and Akaki Kuumeri has a couple of new offerings to enjoy? The new baskets are BBQ Basket and Charcoal Basket. Shortly after being announced on the Mechanical Puzzles Discord, the models were released on Akaki's Picnic (basket packing puzzle series) Thingiverse page. I have to say that it’s extremely nice of Akaki to share his designs with the puzzle community as he develops them. It’s also possible that the new picnic baskets may show up in his AkakiKuumeri Etsy shop at some point.
BBQ offers some things that we’ve seen before as well as something new. I discovered a rotation early on that I thought would be part of the solution but it turned out not to be used. In fact, it turned out that this rotation occurs easily (and often) requiring you to unrotate (derotate, antirotate, counterrotate – it’s really just another rotate). Of course, rotating it back is not as easy as the originally unintended rotate. Once the solution has been found it is easily repeatable. Akaki has designated the difficulty of this puzzle as medium.
The other basket offering from Akaki is Charcoal. Prepare to get burned on this one. I found this one to be much harder than any of the previous baskets (A Tisket A Tasket, Puzzles In – Akaki’s Picnic Baskets, And The After Dinner Mint – Peppermint Basket). I was a bit surprised to see on the Thingiverse page that the level of difficulty is 22.214.171.124. Those are some pretty serious numbers for such a small puzzle. Akaki’s translation of this difficulty level into English is: Unnecessarily Complicated.
This puzzle does a good job of seeming downright impossible. However, once you find a configuration for the briquettes (outside the basket), it’s a simple process to verify that it is correct by checking that you can remove the first piece in 9 moves. Yes, you could consider that a hint being provided by Akaki, but believe me, you will be happy to have received it. Removing the other pieces doesn’t look remotely possible.
One by one, I managed to figure out how to add/remove the final 3 pieces and accomplish the impossible. There are some epic moves within this basket that will amaze you. Little did I realize that I had just completed the easy part. Unfortunately, knowing how the pieces have to move and actually making them move that way are two completely different things altogether. Things have to be moved/rotated in places that are mostly out of reach.
I printed the contents of this basket in the same format as all the previous ones – small and tight. That was a big, Big, BIG mistake! Don’t do it! You’ve been warned. I have fairly thin fingers and really struggled to make the moves. If your mitts are adorned with large sausages, you don’t stand a chance.
Besides getting burned on this one, why is it called charcoal? I believe that it gets its name from the nice sparkly black filament that Akaki had on hand to print the puzzle. I felt compelled to also use a sparkly black filament as well, but since I had already used it for the Salmiakki Basket, I used a Hilbert pattern top layer fill to distinguish the pieces. This gave the briquettes a rougher texture and ironically, a more charcoally look.

The puzzle arrives in a very recognizable orange box. In this case, the box had a black bag attached to it. This bag contained a black towel, a description of the ResQ backstory and goals, and a Reset Guide.
The towel was a nice touch. Many SD puzzles are susceptible to having small pieces fall out and roll out of sight. Most puzzle gatherings aren’t complete without someone swearing at pieces rolling across the floor and groups of people on their hands and knees looking under the furniture. Oh, how I miss the look of horror on their faces. CD decided to preempt that experience and provide an official towel to work over.
Inside the orange box is another box nicely made from Hawaiian Koa. It has various square, rectangle, and rounded slots cut out of it. Inside the box are pieces made from Canxan, Catalox, Bloodwood, and Chakte Viga. So far, nothing unusual. It looks like a typical packing problem with the pieces already packed in the box.
The first odd thing of note is the face of an alien with a strange sparkling hair bun on the top of the puzzle. Apparently, this is a visitor from another dimension and the goal is to rescue the visitor as well as the components of his spaceship from the void (aka the inside of the box). There is obviously some time/space warping occurring inside the 3x3x3 box since you need to extract a spaceship (made from Paduak and Walnut), two antenna assemblies, a silver fuel disk, a gold reactor orb, and a six-orb navigation AI module. I was tracking it all until the end. How could you possible get a six-orb navigation AI module in there? Well, I was quite surprised when it unexpectedly showed up – on the towel – as if by magic – out of the void – Uh Oh!
It looks like there was at least one design change after the box was made. There is a feature that did not appear to be used and caused me to hunt around for something that I may have missed or lost. I guess that you could just call it a space fish on a long wavelength.
The SD aspects of ResQ are very well done and obviously required a fair amount of experimentation to ensure that everything worked as expected. However, the real challenge is manipulating the vortex to get things where you need them. Once you have that figured out, everything is much easier.
I can’t stress enough, that everything is so well made that it looks innocent when in reality, it packs a lot of puzzling in a small amount of space. The Mechanical Puzzles discord had several messages from puzzlers with difficulty finding out how to unlock the vortex at the beginning since it was so well hidden.
I was initially reluctant to look at the reset instructions to put everything back together, especially since it has a ** SPOILER ** warning, but I’m glad that I took a peak and looked at it. Although it does have some spoiler information that you wouldn’t want to see before salvaging everything from the vortex, it basically provides the initial configuration of the vortex. Of course, you can store the vortex in another configuration, but I’d bet that the initial configuration is probably designed to require the maximum number of moves to solve. Don’t be afraid to use the Reset Guide. In fact, the final goal recommends using the diagram to reset ResQ.

ZenPuzzler has reached the end of its second year. I was originally worried that there wouldn’t be anyone reading the blog, but I’ve since received confirmation that, indeed, there are people that have seen the blog. However, I’m not the least bit discouraged by the requests from designers and craftsmen requesting that I don’t blog about their puzzles.

The name of each post is linked to the entry so that you can easily jump to it by clicking on the name.

Every once in a while you need to do something different. This desire drove Brian Menold from Wood Wonders in search of a puzzle to make like Trikado. Brian is a fan of board burrs and when he found Trikado by Yavuz Demirhan, he couldn’t pass it up. It looks like a 9-board puzzle, but 3 pairs are actually combined to provide a 6 piece puzzle.
I like how Brian made the boards with two contrasting woods. Since all the boards have the same 2 toned appearance, nothing of the solution is given away. This particular copy is made with Canarywood & Mahogany.

Like a Dead Skunk in Your Tire Well, Some Things Just Don’t Go Away - Completely Broken Soma, Part 2
The smart thing to do is fling the design deep into the pit of eternal stench. So I bought a 3D printer and attempted to plasticize the design myself. I went with the 3 color version and created the design files to print the required 54 half-cubes. The 48mm (1.9”) cube only took a little over 10 hours to print.
Having suffered a similar fate when creating the wood version, I knew exactly what to do. I shoved the puzzle in a dehydrator and slowly drove the temperature to just over 130 degrees, the low end of the glass transition temperature for PLA. I didn’t want to risk going higher and potentially fusing the pieces together. Shortly after the target temperature was reached, I pulled it out and quickly clamped it for the night. In the morning, I unclamped a reasonably cubic object and disassembled it to ensure that nothing was unintentionally fused together. Having finally exorcising that caustic concept from my system, I quickly put it in a box and sent it away to plague someone else. I really don’t understand why I don’t have friends any more.

Like the prior 13 picnic baskets (A Tisket A Tasket, Puzzles In – Akaki’s Picnic Baskets), the Peppermint pieces fit within the same picnic basket. However, the first thing that you will notice is that the pieces have diagonally cut half cubes. These cuts allow for some new types of movements/rotations needed to solve the puzzle. The second thing that you will notice is that there are only 3 pieces and that there is a lot of empty space in the assembly.
This puzzle is reminiscent of Andrew Crowell’s Turning Interlocking Cube (TIC) puzzles where the difficulty is getting the first 2 pieces situated within a frame against their wishes. I printed the standard version of Peppermint with the tighter tolerances and the rotation required to resolve the positioning of the first 2 pieces is very precise and not easy to discover. There are also several almost possible rotations, but don’t be tempted to force it. One of these almost possible rotations is associated with a false assembly. I’m sure by now that you can tell that I spent a bit of time trying to solve this one. Getting the last piece in is not difficult, but I liked how the movement worked.
If this is the end of the Picnic Basket series, this was a great final puzzle. Akaki did an awesome job designing this final challenge and made good use of the diagonally cut cubes. More final boss puzzles please!
So why did Akaki label Peppermint as Akaki Basket #16 if there were originally 13 picnic basket puzzles? What happened to 14 and 15? If I had to guess, one of those is a prior version of Peppermint that Akaki didn’t release because it had an unintended short cut in the solution. I would guess that the other is:
Puzzle designer extraordinaire, William Hu, took up the challenge to create a picnic basket for the series. Like Peppermint, Nachos uses diagonally cut half cubes. With 4 pieces instead of 3, it was a bit more difficult to find the piece assembly, especially since there is a lot of void space in the final assembly. The empty space and angled cuts also make the puzzle fiddly to play with outside the basket when figuring out the moves required to insert them. The well thought out movements earn this puzzle its difficult rating although I found it quite a bit easier than Peppermint. More please!
Model files for printing your own copies of Peppermint and Nachos are freely available with the other Picnic Baskets on Akaki's Picnic (basket packing puzzle series) Thingiverse page.

Basket puzzles are all the rage now. As one Mechanical Puzzles Discord (MPD) member put it, These baskets are like the current beanie babies of the puzzling world. We had Two Burrs in a Basket by Logan Kleinwaks, 4L Basket and 5L Basket designed by Koichi Miura, 3 Mushroom Basket puzzles designed by Andrey Ustjuzhanin, and now an entire series of Picnic Basket puzzles by Akaki Kuumeri.
AkakiKuumeri Etsy Shop. At the same time, he also kindly made the model files freely available on Thingiverse (Akaki's Picnic (basket packing puzzle series)). Since then he has added 3 more designs and at least 1 more is currently under development.
The picnic basket puzzle descriptions below are in the order that I printed and solved them. With almost 3 hours required to print each, there is plenty of time to solve each before the next one is ready. I printed them directly from the Thingiverse STL files and the fit is perfect. If you turn the basket upside-down the pieces won’t drop until you lightly tap the basket. Each model also has a looser fitting option if you find that the pieces are coming out too tight on your 3D printer. The difficulty levels indicated are those provided by Akaki on Thingiverse or Etsy.
Of course, before printing the first set of pieces, I needed to print the basket. I have to say that the fancier basket model is very well done and imparts a huge cuteness factor to the series. Many members of the MPD proudly display pictures of their printed baskets. Egg Basket consists of 4 pieces that have to be placed in the basket. I found it to be easy, but it is a good introduction of how the pieces can be manipulated and inserted into the basket. The 3 rotational moves are staples for the entire series.
Wine Basket seems to be a favorite on the MDP and for good reason. It’s a bit more of a challenge than Egg and makes great use of the handle to trap pieces. I particularly liked the piece that consisted to 2 connected 2x2 blocks. It interacts nicely with the basket and other pieces. This puzzle itself is worth printing out the basket along with the Wine pieces even if for some reason there was something wrong with you and you weren’t interested in the entire series.
Sandwich is a nice example of how pieces have to work with each other. I didn’t find it that difficult, but it was a nice solve. The reason I started with Egg, Wine, and Sandwich was the Cubicdissection announcement that these 3 puzzles will be made as a set and included in an upcoming release. Eric Fuller also indicated on the MPD that the basket for the CD release would be compatible with the puzzle pieces from Akaki’s Etsy shop. A very nice gesture for those who will want to acquire additional pieces to enlarge the set. Of course, it would be even nicer to acquire the remaining sets of pieces in different exotic woods. After having done the entire series, I agree that these 3 make a nice set although I may have been tempted to swap out Egg for one of the more difficult ones, but that’s just my preference.
Unfortunately, I chose to do Subway after Sandwich. Please avoid doing that. They are similar and use the same solving method. The only real difference is that Subway combines 2 of the pieces to make it a 3 piece puzzle. There is certainly nothing wrong with it, but it was a quick solve for me right after Sandwich.
As a medium puzzle, Coffee Basket is pretty straight-forward. Nothing really difficult and I didn’t find it as interesting as Egg. I should mention that I only printed one basket and have been swapping the pieces in and out so there is no real need to skip any of these puzzles when it takes less than 3 hours to print each. Akaki also provides the option on his Etsy site to buy each puzzle with or without the basket.
Luckily, I had a number of filament colors so that I could print each puzzle in a different color. Unfortunately, I ended up with some odd things like blue hamburgers. Hamburger Basket is one of the 3 puzzles added after the first set of 10 on Thingiverse. Personally, with only 3 pieces and some obvious piece positions, I thought this one was easy. However, I should add that Hamburger Basket is a favorite on the MPD.
When I mentioned to my Non-Puzzling Significant Other (NPSO), a full-fledged member of the Spouses of Addicted Puzzlers (SOAP) club, that I was only planning to make the difficult and medium puzzles, she said WAIT A MINUTE!. Witness the power of the cuteness factor! So I had to change my plan and not only make them all, but print one of the easy ones next. Enter Fruit Basket. Not expecting much, I set about putting the pieces in the basket and didn’t find it as easy as some of the more difficult puzzles. It also added another movement in the basket solving arsenal. I decided that this one was a bit underrated or at least no simpler than some of the medium level puzzles and decided not to offer it as a starting point for my innocent NPSO.
Chicken is not that difficult and expands on the new move from Fruit Basket. It also has one more trick up its sleeve to make it interesting. Just when it looks like it would be trivial, the pieces conspire to get in each other’s way and require you to figure out some additional steps to stuff that chicken in the basket.
Chocolate Basket – Akaki Basket #1, Difficult.
Chocolate Basket is a great design. The only problem that I had with it is that by this time I was familiar with all the moves required and it was a quick solve.
Before now, I’d never heard of Salmiakki. I assumed that it was some sort of Japanese sushi dish but it turns out that it is a licorice made with salmiak salt. Who knew? I found Salmiakki Basket to be tricky and it had me going in circles for a bit. Just when you think there couldn’t be something new.
As the name implies, this one was cake and lived up to its rating. You could easily skip this one. However, if you are like me and only printed a single basket for all the puzzles, it’s not really a big deal to print out the pieces for a particular puzzle. On the MPD there are puzzlers in both camps with some printing a basket for each puzzle or like me a single basket for all the puzzles. There are some that have even printed out a scaled up copy of the basket to hold the pieces for all the puzzles when not in the official basket.
Ice Cream is definitely easy and a nice follow-on to cake. It even introduces a new type of move, which is impressive considering that it was the twelfth one that I’ve done. The variety of different types of movements is surprising. Akaki mentioned that his design process consisted of developing a piece with interesting movements/rotations and then subtracting that piece from the cube space to then be further cut up into other interesting pieces. Of course, given the interaction among the pieces, this description is a very simplistic summary of a more intricate process.
And then there was Vegetable Basket. I found this easy puzzle to be the most difficult of the bunch. I’m embarrassed to say that I spent more than an hour trying to solve this one. Although the move count is not high, there are multiple cube assemblies that can be made with the four pieces requiring you to find the correct one as well as put it in the basket. I kept doing the same things over and over and ending up with the same assemblies that I couldn’t convince myself would go in the basket. It was insane and I was becoming so myself. I was pondering a new name like Basket Case for this puzzle. Thanks to my NPSO for not letting me miss out on the frustration. For an easy puzzle, I highly recommend this one.
Akaki has mentioned on the MPD that he is working on an even more difficult “Boss” puzzle (codename: Peppermint Basket) to cap the series. Of course, the MPD members have indicated that they don’t want to see the series capped, but continually expanded beyond the “Boss” puzzle. Other well-known puzzle designers on the MPD, like William Hu, are also considering contributing to the series (codename: Nachos Basket). I’m looking forward to seeing how this series evolves, especially after seeing some photos involving angled half-cubes.
Finally, a big thank you to Akaki for making the Picnic Basket models available to the puzzle community!

Mini TV consists of a frame with 2 core pieces that run through its center and 6 mini transverse pieces that slide along the outside and impede the movement of the 2 core pieces. I originally looked at using a 13 mm voxel size but the print time was much too long. Changing to a 10 mm voxel dropped the print time to a mere 13 hours.
The puzzle is very approachable and not too difficult to solve. Of course, since it was printed, it was an assembly challenge. It takes a lot less time to solve than to print. It took about an hour to assemble the puzzle.
The assembled puzzle is very attractive and like the assembly is very approachable as a disassembly challenge. The only issue that I had with the design is that the transverse pieces have a tendency to rotate out from the puzzle when they are moved from their initial position. You have to constantly ensure that they stay within the frame to avoid rotational shortcuts while solving.

My break from blogging has been rather rudely interrupted with the arrival of Alan Lunsford’s new sequential discovery puzzle, Bolt Action. It is reminiscent of Alan’s prior sequential discovery puzzle, Unsafe Deposit (Hiding Money in Puzzles - Unsafe Deposit). Like Unsafe Deposit, Bolt Action is a cube with a US quarter peeking out a window, various holes and slots in the cube, and a bolt screwed into one of the sides. The new cube is gray with the name of the puzzle embossed in Black. In one of the square openings, you can see the end of a long bolt wobbling about, but it’s secured on the other end.
The puzzle arrives with a card specifying the goal to remove the coin and find a reason to smile. What does that mean? Doesn’t everyone smile when the coin is released? All I can say is that you will know when you are not done and then when you are.
After seeing various comments about Bolt Action, I expected it to be a similar experience to Unsafe Deposit. I expected to knock this one out quickly and decided to keep track of the solve time since Unsafe Deposit was so quick.
After an hour, I had to step back and reevaluate the situation. My options were: 1) I got really lucky on all of Alan’s previous SD puzzles and was now faced with having to really solve one the right way, 2) My mental facilities have started to decay during the quarantine, 3) Something was wrong with the puzzle. Although all three were just as probable, I opted to pursue #3. Just after the hour mark, I went out into the garage to look for the box that BA came in. I shook it and was rewarded with something rattling in the box. Sure enough, there was a bolt sitting on the bottom under the filler paper.
Am I bothered by the fact that I spent an hour trying to solve an unsolvable cube? Not really. I enjoyed spending time thinking about how the puzzle worked. It’s clever and very well made. And yes, it’s very much on the order of difficulty as Unsafe Deposit. You can get your own copy of Bolt Action on Alan Lunsford’s layerbylayerpuzzles Etsy shop.
This was just another reminder to carefully unbox puzzles that you receive in the mail. There are many sad stories from puzzlers that inadvertently threw away a puzzle piece or extra puzzle. This first happened to me when I accidentally threw out the chicken poop from Eric many years ago now (This Puzzles No Turkey - It's Chicken).

Pure marketing genius! And Eric Fuller is that marketing genius behind Cubicdissection’s branding drive. Pavlov would be proud to see the puzzling masses salivating over the sight of cardboard boxes secured with orange tape.
When Inaccurate Burr was released in 2016, acquiring a copy was a no-brainer. What’s not to like? Designed by Junichi Yananose, make by Eric Fuller at Cubicdissection, and Oh, that beautiful Marblewood!
As per my wont, I quickly disassembled the burr without paying too much attention so that I could attack it as an assembly process. Only when I had it apart did I realize that I was a tad impetuous and should have looked at it first to see why it was called Inaccurate Burr. I’d like to be able to say that this is a rare occurrence, but it seems to occur often. My favorite is pulling out pieces of a puzzle that I had disassembled years ago with no idea what puzzle it is or what shape it’s supposed to make. And of course, the ultimate experience is when you acquire pieces of a puzzle with unknown origins. Some puzzlers even have their friends disassemble multiple puzzles and mix the pieces to provide the penultimate solving experience transcending the normal single puzzle experience, which as you already know, is quite powerful.
With the first pair is established, it is a fairly logical progression to add the others. One piece of the pair has a knob that sticks out one-third and one of the remaining four pieces has a notch one-third deep. Three pieces down! Another piece can’t go anywhere except to be the third piece’s mate. Four pieces down! For the last pair, you would be forgiven if you tried to put them in backwards. It looks like either way may work, but if you pick the wrong one, you will hopefully, quickly realize and rectify the incorrect positioning. Once you get it correct, it ONLY takes 9 moves to insert that last piece and get the puzzle into its final inaccurate shape.
This puzzle may not be difficult but it is nice addition to a 6-piece burr collection and looks awesome in Marblewood.

Although it has taken several decades, I finally found something tangible that explains my college motto: Per Aspera Ad Astra - through adversity to the stars. This something comes from the fiendish mind of that Turning Interlocking Cube (TIC) master Andrew Crowell, who knows that the only thing better than a puzzle is a cluster of puzzles. With that in mind, he embarked on creating a series of StarTICs. Of course, he attempted to pack as much adversity as possible within each to entertain us along the journey.
The StarTICs occupy a 5x5x5 cubic dissection space. Each consists of a gray shell surrounding an inner 3x3x3 core with a unique color for that StarTIC. Although the core appears solid, each is comprised of several pieces. The objective is to have the core go critical and eject its mass from the center of the shell. Bits of the shell may remain stuck to the pieces while some bits of the core may be left behind on the empty shell.
After careful examination, you can determine that 3 of the 4 shell vacancies look like they can be satisfied by 2 of the core pieces. The fourth can only be completed by one of the core pieces but it can go in that spot in 2 different ways. However, it is immediately obvious that only one of them makes sense. Once that piece is in place, it is obvious where the other 3 core pieces have to go. The only thing left is to determine the order and movements required to get them in place. Of course, some rotations will be required, but they are minimal.
My favorite rotation involves the “T” piece that gets translated halfway through the rotation. I designed a puzzle around this type of move about a decade ago called Interrupted. It was the only thing that this puzzle had to offer. One of the reasons that I like Andrew’s puzzles so much is that they have so much more to offer than just a single interesting move.
If you are tackling this as a disassembly challenge, you appear to be presented with a catch 22 situation. It looks like a 2 block chunk of the shell connected to one of the core pieces needs to be removed to get the core pieces out. However, it also looks like this piece can only be pushed into the core and not pulled out. It appears that the main challenge is to figure out how to remove this plug from such an obvious exit portal. Or is it? You’ll have to see for yourself.
As an assembly challenge, you need to discover the very specific order of adding and rotating the pieces to the frame including plugging that 2 block gap in the shell. Of course, when adding the first few pieces, a lot of movement and rotations are possible. Even fully assembled, quite a bit of movement is allowed.
With either the disassembly or assembly, it is not difficult to figure out what is going on within this StarTIC. Rotations and movements are straightforward and shouldn’t prove to be difficult for most users. If find yourself intimidated by this cluster, start with StarTIC 3.
The assembly process is a lot of fun with StarTIC 4. All the core pieces have a piece of the shell attached and aren’t difficult to place. However, finding the right order to add, move, and rotate them will be challenging, especially considering the lengthy sequence of movements and rotations to get all the core pieces in place once the last one has been added to the shell.
The StarTIC cluster is a worthy addition to Andrew’s TICs. Not a single loser in the bunch - they’re all stars!
